What Is the Root Canal Therapy Instrument? The root canal therapy instrument can also be called a root canal motor. It is a precision electronic instrument designed to reduce the work intensity of the doctor, replace the manual enlargement of the root canal, enhance efficiency and save time, and prepare a more standard root canal.

The dental underlying canal treatment tool is among the healthcare instrument of stomatology, which includes two parts: the irrigating tool and the suction gadget. The eliminating gadget allows the pressurized air to get in the eliminating head with the water pump, air storage space tank and flow regulating device. The suction power device draws out the necrotic cells within the root canal through the filtration system, vacuum, shut-off valve, exhaust device, flow regulating valve, suction head. The suction head is a key area of the instrument. It contains elastic contacts, Root Canal Needle tubes and manages. The elastic connections can be produced into wedges. The tool brings together watering and suction power, which can safely and rapidly draw out the necrotic elements within the root canal of the teeth, so the teeth can be taken care of smoothly.

In accordance with the operating basic principle in the underlying canal treatment tool can be divided into: ultrasonic root canal treatment instrument and microscope root canal treatment instrument.

1. Ultrasonic Underlying Canal Therapeutic Equipment

The ultrasonic root canal treatment instrument is made up of an ultrasonic emission system plus an irrigation system. It provides two cleansing techniques, chemical and mechanical. The “cavitation” effect of ultrasonic surf can greatly enhance the antibacterial effect in the watering solution, which can necrosis inside the underlying canal. Cells and toxins are flushed out. Its working principle is to use the ultrasonic launch system to help make the increase needle (as shown in the figure) vibrate 3-dimensionally, plus the liquid squirt system for root canal planning.

The main advantages of the ultrasonic root canal treatment instrument are: the ultrasonic technologies have biological effects, mechanical results, thermal effects and cavitation phenomena that mix the above 3 functions, and can effectively kill different bacteria within the root canal. Ultrasonic root canal preparation has good continuous watering, which can well-timed remove necrotic cells particles within the underlying canal, successfully decrease the quantity of microorganisms within the underlying canal, and avoid the piston action of the instrument inside the infected root canal. So the infected material in the underlying canal is not easy to exceed the main apex. Because of the vibration of the ultrasonic file itself, it is much less laborious to perspective and pull with your fingers. It only must carry out the raising and inserting movement as opposed to the revolving motion, and so the breaking up price in the unit and the incident rate of the device dropping into the mouth from the patient and becoming swallowed accidentally are reduced. Due to the fluid spraying gadget, there is not any must stop for flushing, saving procedure time.

2. Microscope root canal treatment instrument

Microscope underlying canal therapy tool is a mix of microscope technology and medical technology. Dental care apex locator can clearly notice the tooth body structure and root canal morphology. Whether it is conventional root canal treatment or apical microsurgery, it can permit physicians to safeguard the standard tissue of patients, therefore enhancing the rate of success of therapy, shortening the recovery time, and reducing discomfort. , The postoperative wound is smaller sized.


1. Built in rechargeable battery, easy to operate. Power supply display (shows the strength of the built in battery power, flashes when charging), torque show (displays the torque once the motor unit is working), speed display (100~625r/min) The speed of every equipment raises or reduces by 25r/min.

2. This machine has a number of memory functions, doctors can set different torque and velocity according to various kinds of growth needles, easy to operate.

3. In the process of expanding the root canal, after the expansion needle torque surpasses the set value, in order to stop part penetration and needle damage, the electric engine will instantly reverse, and the doctor can also adjust the manual turning from the machine based on the real scenario.

4. The machine adopts a big Liquid crystal display display screen show, which can intuitively see the operation in the machine on screen.

5. In order to minimize the financial stress in the doctor and much better sterilize the problem, utilize a 1:1 reduced-speed bending head along with a much better Endodontic Plugger.

Precautions for use

1. To control the torque and speed, it is advisable to set the torque control motor and the coordinating speed. After the torque recommended through the broadened needle producer, speed is extremely necessary for therapy security.

2. Determine the duration of the tool every time it gets into the main canal. Longer instruments increase the chance of twisting and breaking up. Equipped with root canal duration calculating instrument, caliper, etc. for working duration way of measuring.

3. Correct operation is vital: tend not to use stress and force in the tip. The main Root Canal Instrument must not remain in the main canal for too long.

4. The damage from the tool mainly occurs in molars, especially in the slim and narrow root canals like the top canal and mandibular molars. The mesial root canal should be treated with great care before treatment.

5. Curved root canals, re-treatment and calcified underlying canals need unique equipment and techniques, and it is advisable to make use of a new expansion needle.

6. Begin a directly path to maintain a sleek underlying canal, pay attention to actions throughout operation, and try to ensure that the expansion needle as well as the root canal path have been in line to lessen the twisting resistance in the growth needle in the crown and the stress on the tool.

7. The main canal ought to be kept sufficiently moisturized and rinsed every time it really is ready.

8. Because the internal underlying canal is slim, do not apply stress towards the expansion needle during procedure. The reducing needs to be finished solely by the strength of the machine alone and the sharp fringe of the increase needle.

9. In the case of inadequate experience, it is actually most secure to make use of the recommended minimum torque. Generally speaking, lower speed will extend the clinical lifetime of the product and lower the chance of breaking up.

10. Pick a great growth needle and control the number of times of use: when you use it, you should notice regardless of whether there is certainly cable sketching or deformation. If you locate something, you must dispose of it soon enough, or you will be sorry.

11. After each use, it is recommended to record the vwpszr number of uses to stop exhaustion of the tool; the debris of the expanded needle edge needs to be cleaned repeatedly in time and designed with a cleansing desk.
